Every country in the world is supposed to work to further the interests of its citizens (in accordance with human rights, international agreements etc).

Trying to appeal to some higher ideal of "free market" between countries is just silly. Did China and EU sign a comprehensive free trade agreement when I was asleep? (as Netherlands is an EU country and all cross border trade lawmaking is offloaded to the EU). If not, they really should just shut up.

There of course exists a World Trade Organisation which is like a treaty that essentially says "we're not going to engage in targeted regulation", but it has caveats "unless it has to do with national security" and few other things. So it's really a framework to facilitate trade rather than a global free market.
